ICE CAN.

Application filed May 17, 1924. Serial' No, 714,152.

This invention relates to ice cans for use in raw water plants. In such plants it is usual to agitate the water in ice cans by means of a jetof air discharged into the water near the bottom of the can. The preferred location for the air jet is at or near the middle of the bottom of the can, butsuoh a location oit the air jet has heretofore involved ditiiculties because the rair pipe must be led vthrough the bottom joint fiange of the can and it has proven impracticable prior to my invention to lreep the joint tight around the air pipehole.

(lne feature ot the present invention'resides in a special construction which precludes the possibility of suoli leakage.

Another feature of the invention resides in the means adapted to permit the ready re moval and replacement of the air pipe. rllhis a matter of Vconsiderable difficulty in the case of so-called multiple can units in which a number of cans are rigidly mounted in ay supporting frame.

I lt is now the practice to equip such units extending the length of the unit, and with a 3lurality of branch pipes leading from the lateral to the cans, and housed in the narrow intervals between adjacent cans. The space between cans is so limited that itis difficult to provide a construction. for the branch air pipes such that they may be removed and replaced without c isturbing thel air lateral, and withf out removing any of the cans from the frame.

This invention provides a construction of this type which also permits the air to be delivered 'through the bottom of the can.

A preferred embodiment of the invention is illustrated in the accompanying: drawing.y

in which:

F 1 is a fragmentary1 side elevation showing portion of the supporting frame, and thre of the cans supported thereby to- Vgether with their air connections;

Fig. 2 is a section on the line 2-2 of Fig. f1;

Fig. 3 is an enlarged section tl rough the bottom ofa. can on the line 3-3 of Fig. 2; Fig. 4 isa plan view of the bot-tom conrectionshown in Fig; V 3;

lig. fitting lateral with the branch pipes;

Fig. 6 is a fragmentary View similar to Fig. 3. showing a sliffhtly modified construction.

The supporting framework of the can unit may be of any desired construction, and is not illustrated in detail. The side members of this frame are indicated at 11, and the supported cans are shown at 12. These cans are provided with reinforcing bands 13 at their mouths, as is usual.

Mounted on one side member 11 are a number of'fittings 14e which supportthe air lateral pipe 15. The fittings 14 are `best shown in detail in Fig. 5.

Each fitting 1st is bifurcated and straddles the side member 117 to which it is connected by screw 16. It is provided with a port 1 7 which connects the air lateral 15 with hollow manifold 18. Extending through the manifold 18 are two shouldered tubular members 19, one for each of the branch air pipes 20. The tubular members 19 are formed with a iiow regulating constriction 2l., leading to a. port ,22, which communicates with the interior of the manifold 18. The members 19 are threaded at their ends to receive cap nuts 23. The cap nuts 2 5 is a. section showing in detail the preferably used to connect the air retain the members 19 in place and tight i joints are afforded by means of gaskets 24.

The nuts 23 serve as guides for the heads 25 of clearing stems 26, which are moi/'able through the constrictions 2l to clear the same. Each stem 26, adjacent the head is provided with aflange 27. and gasket 28. A coil spring! 29. surrounding the stem 26 and contined between the end of the tubular member 19 and the flange 27, serves to seat the gasket against the inner face of the nut thus preventing leakage around the actuating head 25.

By pressing` and the clearing stern 26 is moved releasing the head 25, longitudinally Vthrough the constriction 21, and serves to clear away any scale or other obstructions.

This constructionV provides `a very convenient fitting for use in ice cans because the removal of the nuts 23 permits the withdrawal 0f the tubular members .19, thus free ing the pipes 20. without 'rotation of e branch pipe. ln this detail it has some ot the characteristics of a union fitting though specifically different therefrom.

The reason tor connectingT two pipes '20 to a single manifold 1S is to reduce 'the ntunber of branch littines required. since it is possible to locate two air pipes `tor two atlj.cei1t cans in the interval between these two cans (see Fig. l).

Referring particularly to Fig'. 2, it will be observed that the air pipes 20 are `:given a gradual down vard curvature, and then extend downward along the sides olil the cans to pointsl near the bottoms thereoi. '.lhe `gradual curvature is to permit the pipe to yield to any dillerential expansion ot the pipe relatively to the can. yhis 'feature is not specitically claimed herein as my coptfndinb application Ser. No. 'T14 153, tiled May l. L192i contains canins directed thereto. Near the bottom of the can (sec Figs. il and l) each pipe iO bends` shaipljY inward toward can. and passing through the bottoni flange 3() of the can is connected to :in angle litting 31. This angle fitting 3l is threaded into a flanged plate l2 riveted to the bottoni of the can. The flanged plate may be either on the inner or outer side of the bottom plate 3:53, one arrangement being shown in Fig. 3, and the alternative arrangement in G.

ll"hc 'connection between the tube 20 and the i'itting 3l is a special type ot` union. l `ittingclosely on the end of the tube 2() revcrsely beveled ringY or sleeve 3l, otl relatively soft metal. This is received in a conical recess formed in the end ot` the littinpr 3l and in a similar conical recess formed on the inner tace et the nut 35. which is threaded on the end of the fitting 3l. The ring;- 3% is thus compresse( around the end of the pipe 20 by screwing up 'the nut 35, but after the nut 35 has been removed it is possible to withdraw the ring' Si from the end of the pipe.

To prevent leakage where the pipe Q5) passes through the joint flange 3l) oit the can, a reinforcing eyelet 3G used. It is necessary to `form the hole tor the air pipe after the flange 30 has been formed7 and con sequently after the bottoni joint ot the can has been niade. After the hole is punched, the bottoni flange is dipped in solder and then the eyelet 36 is set and sweated in place. Y

Finally. the tian'ge with the eyelet in place is again dipped in solder to insure an absolutely tight joint. The eyelet 36 reinforces the tlanleje where it is weakened by the formation of the hole and the use of the eyelet produces a joint 'which is absolutely tight. and wil-l 'remain so.

The eyelet 3G is :set near the bottoni of the thinge and this permits the withdrawal of the air pipes 20. To remove a pipe, the mits 29 and 35 are unscrewed. The clearingY stems :'26` with their springs, are removed with the nut 29, and the ring 3l and nut 35 are withdrawn from the end of the pipe. It is then possible to withdraw the tubular member lf) trom the manifold 1S, swing the pipe 2f) downward out ot' the space between the two cans, and finally withdraw the pipe from the eyelet BG. This pipe, or a similar pipe, may then bc put in place by reversing:r the operations just described.

The special type ot union shown in Fig. i3 is impmtant. because the removal ol the ring; Illpeiinits the removal olf the nut 215. lt thus makes it possible to usc an c vclct 2in only slightly larger than the pipe 2u.
